Ordering only Pana FC cap from digkey cost ~ US$25. But sure if it worth doing it

I would say that real advatages of snubbering electrolytics are unclear at best, depending on best guess values and so on.
In some cases(at least on Spice simulations) added 100n+0.1R can even lead to worser result than el-caps alone.

You can download switchercad from linear website wich is free spice simulation software and do your own snubber simulations.

If you want to gain some real advantage you have to go to SMD and small components.
